SKF KM 20 Bearing Lock Nut

The SKF KM 20 is a precision bearing lock nut used with an MB-series locking washer to secure bearings, adapter sleeves and withdrawal sleeves on threaded shafts of around 110 mm diameter. It provides a reliable, vibration-resistant axial location that maintains correct bearing clearance and prevents loosening under the cyclic loads typical of rotating equipment.

Machined to SKF's quality standards, the KM 20 ensures square, even clamping against the bearing inner ring, which is essential for long bearing life in the heavy continuous duty of Saudi industrial plant. In the high ambient temperatures, vibration and dust of the Kingdom's refineries, desalination stations and mining operations, a secure lock nut prevents the gradual loss of preload that leads to premature failure.

The KM 20 is used at facilities such as MAADEN (Gold mine conveyor drive systems) on pumps, fans, gearboxes and shaft-line equipment across the oil and gas, petrochemical, power and mining sectors.

The Kingdom of Saudi Arabia's industrial expansion under Vision 2030 — spanning new refining and petrochemical capacity, the NEOM and Red Sea giga-projects, expanded desalination and water-transmission networks, and growing mining output at MAADEN — is placing record demands on the reliability of rotating equipment. Operators at sites such as Saudi Aramco (Khurais water injection facility) increasingly rely on genuine SKF components and correct maintenance practice to maximise asset availability, reduce energy consumption and avoid the high cost of unplanned shutdowns. Counterfeit and non-OEM parts remain a real risk in the regional market, so sourcing authentic SKF products through an established distributor protects both equipment and warranty coverage. Razz Middle East supplies only genuine SKF product backed by full traceability and SASO documentation, with experienced technical staff able to advise on selection, interchange and application for the demanding conditions of the Saudi market.
